Application flied December 20, 1899. Serial No. 740,977. (No model.)

To all whom it may concern:

Beit known thatI, GEORGE SATTLER, a citizen of the United States, and a resident of Elkhart, in the county ofShebo'ygan and State of Wisconsin, have invented certain new and useful Improvements in Insect-Screens, and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention has especial reference to that class of screens which have openings or passages therein to enable flies or other insects which alight upon the inside of the screen to find egress upon the outer side thereof; and to that end it consists in certain peculiarities of construction and combination of parts, forming a novel screen of this general character, all as will be more fully set forth hereinafter, with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 is a vertical sectional view of a screen embodying my present invention, taken on the line 1 1 of Fig. 2. Fig. 2 is a view in elevation of said screen looking from the outer side toward said screen. Figs. 3, 4c, and 5 are transverse horizontal sectional views taken on the lines 3 3, 4 4, and 5 5, respectively, of Fig. 2 and looking in the directions indicated by the arrows.

Referring to the drawings, A 13 represent the top and bottom parts, and O D the sides, of a rectangular frame of any suitable construction made, preferably, of wood, the said frame members being preferably made double to receive between the meeting surfaces of each double part the adjacent edges of the upper and lower screen-sections E F, preferably formed of pieces of ordinary screen material, commonly known as wire-netting or wire-gauze. In the form of frame shown the inner meeting edges of the double parts of the frame are shown rabbeted or recessed a proper distance, so as to receive between them the edges of the wire screen, and it is obvious that, if preferred, each part of the frame may be made in one piece and provided with a longitudinal groove or saw-kerf for this purpose or that the described pieces E F of the screen may be simply attached to one outer surface of the frame, if desired in any instance, it being only requisite that the said pieces E F shall be securely attached to the frame, with their opposed inner edges separated a proper distance, as best shown in Fig.

.1, the relative height of the two pieces E F,

and hence the exact location or vertical height 5 5 of the space between them, being immaterial, though it is desirable that the points of egress hereinafter specified should be near the upper end of the screen, as it is the custom of insects when on a screen to move in a gener- 6o ally-upward direction. Extending entirely across the screen from side to side thereof is another strip G of the same material, which has been crimped or stamped to form a series of tapering flutes or channels g g g, whose side walls converge upwardly, the fluted strip G entirely, closing the described space between the upper and lower pieces E F and extending a slight distance below the upper edge of the lower piece Rand a much-greater distance above the lower edge of the upper piece E, so that the described flutes or channels g may form therewith tubular passages,the said strip G being applied on the outer side of the screen and the tops of said flutes being wholly open, as shown at e in Fig. 1, while the lower edge of the strip G is preferably bent upwardly, as shown at h in said figure, and the adjacent end walls of each successive pair of flutes g are flattened down and crimped together, as best shown at 'i i in Fig. 5, so that when the strip G is in place in the screen the lower ends of all the flutes g g are closed by reason of said flattening and the described inwardly and upwardly turned lower edge of the said strip G.

The operation of my device will be readily understood from the foregoing description of its construction read in connection with the accompanying drawings. The flies or other insects which alight upon the inside of the screen find their way through the open space fbetween theupper and lower pieces E F to the lower parts of the described flutes or channels g of the strip G, and thence move upward on the walls of said flutes g and out through the open tops thereof at e, and find themselves upon the outer surface of the screen, and as the side walls of the said flutes g converge as they approach the top the egress-openings are much narrower than the inlet-openings, besides which they have a closed wall formed of the upper piece E, and hence even if an insect should seek to reenter said passages this reduction in size over the size of the inlet-openingswould afford an additional obstacle.

Having thus described my invention, what Iclaiin as new, and desire to secure by Letters Patent, is

1. An insect-screen comprising a suitable frame having separate pieces of screen material secured across the upper and lower parts thereof from side to side, and separated by a space, in combination with a strip of like material formed into a series of open-topped flutes or channels, said strip entirely closing the described space between the upper and lower pieces, and extending above the lower edge of said upper piece, on the outer side thereof, to form egress-passages leading from the inner to the outer side of said screen.

2. An insect-screen, comprising a suitable frame having separate pieces of screen material secured across the upper and lower parts thereof from side to side, and separated by a space, in combination with a strip of like material formed into a series of open-topped tapering flutes or channels, whose side walls upwardly converge, said strip entirelyclosing the described space between the upper and lower pieces, and extending above the lower edge of said upper piece on the outer side thereof, to form insect-egress passages, and the lower edge of said strip being turned upwardly and inwardly and flattened to close communication between it and the upper edge of the said lower piece.

3. In an insect-screen, the combination with the screen-frame and a screen secured thereto, and whose upper and lower parts are formed with a transverse opening between them, of an independent continuous strip of screen material, formed into a series of vertical flutes or channels, and secured to the outer surface of said screen, the'said flutes or channels having upwardly-converging side walls, and being wholly open at the top, and wholly closed at the bottom.

In testimony that I claim the foregoing I have hereunto set my hand, at Elkhart Lake, in the county of Sheboygan and State of Wisconsin, in the presence of two witnesses.

GEORGE SATTLER.
